background: visceral leishmaniasis (vl) or kala-azar is a parasitic disease caused by the species of leishmania donovani complex. mediterranean type of the disease is endemic in some parts of iran and more than 95% of cases were reported in children up to 12 years of age. this study was performed to determine the seroprevalence of vl in the rural areas of dashti district from bushehr province. ...
background: this study aimed to determine the seroprevalence of canine visceral leishmaniasis in meshkin-shahr district as endemic areas of human visceral leishmaniasis (hvl) for presenting control program of hvl to health authorities. methods: a seroepidemiological study to determine seroprevalence of canine visceral leishmaniasis (cvl) among ownership dogs using direct agglutination tests (...

building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
experimental study of steel plate shear walls with composite steel infill platesunder cyclic loading
in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...
One of the main challenges in using the Discrete Element Method (DEM) is to specify the correct input parameter values. In general, the models are sensitive to the input parameter values and accurate results can only be achieved if the correct values are specified. For the linear contact model, micro-parameters such as the particle density, stiffness, coefficient of friction, as well as the par...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
